identification of midgut trypanolysin and trypanoagglutinin in glossina palpalis sspp. (diptera: glossinidae).a midgut trypanolysin and an agglutinin from glossina palpalis subspecies were isolated and partially characterized using anion-exchange chromatography and polyacrylamide gel electrophoresis. fplc fractions of midgut extracts of glossina palpalis palpalis caused agglutination and lysis of two trypanosome species (trypanosoma congolense and trypanosoma brucei brucei), although glossina palpalis gambiensis caused only agglutination. the trypanolysin and agglutinin were active only in the posterior ...19902092294
post eclosion age predicts the prevalence of midgut trypanosome infections in glossina.the teneral phenomenon, as observed in glossina sp., refers to the increased susceptibility of the fly to trypanosome infection when the first bloodmeal taken is trypanosome-infected. in recent years, the term teneral has gradually become synonymous with unfed, and thus fails to consider the age of the newly emerged fly at the time the first bloodmeal is taken. furthermore, conflicting evidence exists of the effect of the age of the teneral fly post eclosion when it is given the infected first b ...201122087240
high frequency of (kinetoplastida: trypanosomatidae) type among (diptera: glossinidae) in a historic trypanosoma foci in north-eastern gabon: preliminary study.human african trypanosomiasis became a neglected disease after the 1960s, when case numbers dropped dramatically. it again became a public health problem in sub-saharan africa at the end of the 1990s, when new cases were reported, notably in central africa, and specifically in gabon, where historic foci existed and new cases have been reported. therefore, the present study reports on an entomological survey conducted in may 2012 to determine the pathogenic trypanosome infection rate in tsetse fl ...201627113105
